Title: Refuse disposal system
IPC: F23G5/20
Filed: 1971-12-06
Abstract: 1367339 Refuse disposal; drying refuse KCM INDUSTRIES Inc 6 Dec 1971 [7 Dec 1970] 56438/71 Headings F4B and F4G A refuse disposal system comprises a rotary combustion chamber 30, Fig. 5, having inner and outer sections 70, 72 each having a helical transport vane 74, 76 adapted, as the chamber rotates, to move shredded refuse first from the narrow to the larger end of the inner section and then from the large end of the outer section towards the narrow end. The outer section opens with a rotary residue chamber 32, also provided with a transport vane 33, the chamber having holes through which solid residues face and combustion gases escape being collected by a hood 34, Fig. 4. Before being burnt the refuse passes through rotary drying chambers 26 to a storage bin 46 from where it is fed to the combustion chamber. All the units are enclosed within a single housing 44. Refuse is supplied to the combustion chamber by screw auger 48 and the chamber is initially heated, and a flame maintained therein by burner 94. Liquid waste may be injected through pipe 96. The residue chamber 32 comprises a rotatable perforate cylinder enclosed within a housing 34, 90 and provided with exit orifices 95 communicating with shoot 97 for the removal of large lumps of residue. Fine residue falls through the perforations into a water bath 92 and combustion gases are drawn away through a conduit connected to opening 118 in the housing 34. The drying chambers 24, 26 are inclined upwardly from an input end to an output end in a bin 46 at the head of the combustion chamber. Each chamber is provided with a helical vane the pitch of which decreases towards the output end of the cylinder. A second vane may be provided over the inlet region of the chamber, interleaved with the first. The drying chambers are heated by radiation from the combustion chamber and are supplied with heated air drawn from the housing 44, the air entering the chambers through holes in the cylinder wall from conduits defined by angle irons 56 fixed to the outside of the cylinder wall. A secondary combustion chamber may be provided to treat the combustion gases released through opening 118. The rotational speeds of the various chambers and conveyers may be controlled independently to establish desired temperatures and feed rates.

Title: An improved method of and apparatus for obtaining a continuous indication of the magnitude of grain losses
IPC: A01D41/127
Filed: 1968-12-03
Abstract: 1,241,670. Combine harvesters. CLAYSON N.V. 3 Dec., 1968 [5 Dec., 1967], No. 57199/68. Heading A1F. [Also in Divisions G4-G6] The efficiency of a combine harvester is assessed by counting the number of grains extracted from a sample of material falling from the straw shakers or sieves. This material is subjected to an additional shaking and blowing action to separate the grains from the chaff, the grains falling on to a diaphragm associated with an electric transducer. The resulting signal is passed through a band-pass filter to eliminate noise and shaped before application to a counter in the form of a meter viable to the driver. According to the meter reading the controls of the harvester may be adjusted.

Title: Improvements in or relating to Echo Cancelling Apparatus for Communication Systems
Inventor: UNRUE JOHN ELLISON JR

Filed: 1968-12-04
Abstract: 1,185,000. Echo suppressors. WESTERN ELECTRIC CO. Inc. 4 Dec., 1968 [8 Dec., 1967], No. 57510/68. Heading H4R. In an echo cancelling apparatus in which an adaptive transversal filter 17 synthesises an echo signal from the signal on the incoming pair 13 of the four wire line and subtracts the synthesized echo signal from the signals in the outgoing pair 12, the multipliers of the transversal filter being continuously adjusted in accordance with the result of a cross correlation of the outgoing signal with the signal present at the taps of the delay line of the transversal filter fed with the incoming signal, the residual echo signal, which is still present in the outgoing signal after the synthesized echo signal has been subtracted, is eliminated from the outgoing line signal by a filter 31, which has a high attenuation at each end of the pass band of the system. The residual echo is due to the lack of identity of the synthesized echo signal with the actual echo signal, due to the finite length of the delay line in the transversal filter. The filter 31 may be switched out by closing contacts 32 when a speech detector 33 detects no incoming signal on line 13.

Title: Method and regenerative heat exchange system for heating combustible gas
IPC: F23L15/02
Filed: 1971-12-14
Abstract: 1353550 Thermal regenerators NIPPON KOKAN KK 14 Dec 1971 [22 Dec 1970] 58067/71 Heading F4K The heat transfer unit 1 or 2 of a thermal regenerator is heated up by an oxidizing flame (e.g. from a main burner 6) and then, before a gas to be heated (particularly a highly combustible or explosive gas) is passed through the unit, the oxygen content of the atmosphere therein is reduced by a reducing flame (e.g. from an auxiliary burner 7). When reheating of the unit becomes necessary, the auxiliary burner is ignited burning with a reducing flame which is then changed to an oxidizing flame. Thereafter the oxidizing flame of the main burner is utilized to heat up the unit. The arrangement shown is for preheating coke-oven gas A and blast furnace gas B prior to their entry into a reforming tower 3 from which the reformed gas is ducted at 13 to a blast furnace. The regenerative units 1 and 2 are used alternately to heat the gases A, B. During the heat-up stage of each unit, the burner waste gases pass to a stack 11 which may be purged during the changeover stage by steam 12. Both the main and auxiliary burners may be such as to be usable with either an oxidizing or a reducing flame.

Abstract: 1,242,708. Colour photographic reversal images. AGFA-GEVAERT AG. Dec. 13, 1968 [Dec. 15, 1967], No.59526/68. Heading G2C. A process for the preparation of colour photographic reversal images comprises imagewise exposure, black-white development with a black and white developer which contains thiocyanate ions, second uniform exposure and colour development of a photographic multi-layered material which contains a red sensitive silver halide emulsion layer with a cyan colour coupler capable of reacting with the oxidation product of a colourforming developer to yield a cyan dye, a green sensitive silver halide emulsion layer with a magenta coupler and a blue sensitive silver halide emulsion layer with a yellow colour coupler, in which at least one of the silver halide emulsion layers consists of a mixture of at least two silver halide emulsions having different speeds in which the average grain size of the less sensitive silver halide emulsion is at least 50% of that of the more sensitive emulsion and in which the spectral sensitivity of the two emulsions is substantially the same. In this invention coarser grained silver halide emulsions give improved grain granularity of the image dye. The object of the invention is to improve the speed to grain size relationship of photographic silver halide emulsions, i.e. to obtain the finest possible dye grain with the highest possible speed of the silver halide emulsion.

Patent GB-2026268-A (GB)
Title: Frequency synthesizers
IPC: H03L7/197
Filed: 1978-07-22
Abstract: In a phase lock loop frequency synthesizer including divider 14 with adjustable division ratio N, to enable the controlled oscillator VCO C10, frequency (Fo) to be adjusted in smaller steps than a reference frequency Fr and yet maintain a loop bandwidth greater than the step size with good spurious performance, Fo is made slightly more than N.Fr, and at periodic instances, determined by the period of the frequency difference between Fo and N.Fr, a control unit (28) temporarily increases N by unity so as to bring Fd and Fr into phase. To eliminate the sawtooth waveform that would otherwise be produced on the phase error signal the control unit (28) also produces unit increases in N during each such period so as to produce a phase difference between Fd and Fr which is opposite in sign to, and substantially offsets, the integrated value of the phase differences up to that instant. The phase error signal therefore undergoes only residual variations, and these are backed off by an analogue output (line 34) derived from the control unit (28). <IMAGE>
